Title: Pneumatic grain seed distributor - rate and spread of seed controlled by adjustable distributing impeller
IPC: A01F25/04
Filed: 1973-09-24
Abstract: Grain seed is supplied from a storage container through duct (2) by a low pressure blower unit. The seed is discharged through a profiled exit section (4) downwards onto a distributing impellor (15) driven via a pulley belt unit (18, 21). The way in which the distributing action occurs is determined by the vertical and horizontal position of the impellor relative to the duct exit section. The horizontal position of the impellor unit can be adjusted by sliding clamp section (13) along the duct. The drive motor may also be adjusted vertically by raising the unit via bush (24) and shaft (14). In addition a deflection plate (10) may be set relative to the impellor periphery to limit the quantity discharged.

Title: Tool string shock absorber
Inventor: REID MICHAEL
IPC: F16F7/00
Filed: 1999-07-22
Abstract: An apparatus and method for absorbing shock downhole in a wellbore. The kinetic energy from a moving tool is absorbed to dissipate such energy, to decelerate the moving tool, or to prevent impact damage from contact between the tool and other downhole components. An actuator has an interference fit with a body such as the interior wall of a tubing section. When the moving tool actuates the actuator to move the actuator relative to the body, kinetic energy is dissipated into the body as the body elastically deforms due to the moving actuator. The amount of energy dissipated can be determined from the strength of the body, the contact dimensions between the actuator and body, and the length of moving contact between the actuator and body.

Title: Setting the position of the measurement object in the measurement of layer thickness by X-ray fluorescence
Inventor: KAISER KARL-HEINZ
IPC: G01N23/223
Filed: 2001-03-09
Abstract: In the measurement of layer thickness by X-ray fluorescence, in which a beam of X-rays is directed onto the surface (14) of an object of measurement (16) through a collimator (17) and the fluorescence is detected by a detector (18), the position of the surface (14) is set to a specific position using an imaging device (21) the beam of which is made co-incident with the X-ray beam <I>eg</I> by means of a beam-splitter (23). At the specific position the imaging device is focussed onto the surface and the contrast between adjacent pixels is greatest. This position is determined by changing the distance between the surface and the collimator by an absolute amount, detecting the differences in pixel brightnesses during and after the movement to determine the position of maximum difference in brightness. An approximate scan followed by a precision scan of distance may be made.

Title: Bolt for conveyor belt fastener
Inventor: COLEMAN JOHN B
IPC: F16G3/08
Filed: 2000-09-13
Abstract: A fastener (10) is provided for splicing end portions (18 and 20) of conveyor belts together with the fastener having a bolt (16) with a pilot or lead-in portion (52) that provides improved threading of a nut (40) thereto and makes installation of the fasteners on the belt ends faster and easier. The pilot portion (52) of the bolt is longer than the beveled conical tip portion of prior bolts so that nuts received thereon will stay substantially aligned with the axis of the shank. In this manner, threading of the nut to the bolt shank is easier in terms of avoiding cross-threading problems. Also, as the pilot portion (52) of the shank is free of any threads, the installation of the bolt onto the belt ends can be done more quickly with less resistance during the insertion process. With the threading of the nuts started on the bolt shank threads, the nuts are less likely to fail off the piloted shank when a power wrench is used to screw the nuts down for clamping the places (12 and 14) of the fastener about the belt end as even if the nuts become unthreaded from the shank, the pilot portion will hold the nuts thereon. Further, the lead-in portion free of threads provides a protection area for the endmost threads on the shank that are spaced further down the length of the shank.
